Question

x cos A =1 and y cot A= 1 find x^2-y^2​

Answer 1

Answer:

If xCosA = 1 ; yCotA = 1.

therefore, x = 1/CosA ; y = 1/CotA

A/Q,

=> x² - y²

=> (1/CosA)² - (1/Cot)²

=> Sec²A - Tan²A

=> 1 ans.

Step-by-step explanation:

THNKS MY 20 ANSWER. I WILL INBOX U.

Answer 2

x=1/cos A

y=1/cot A

${x}^{2} - {y}^{2} = { \sec }^{2} x - { \tan }^{2} x \: = 1$
